Dev notes

Add console color codes

enum AnsiColorCode {
    Red = 31,
    Green = 32,
    Yellow = 33,
}
// Add color to text in the terminal output
function decorateStringWithAnsiColor(inputString: string, decorationColor: AnsiColorCode): string {
    return `\x1b[${decorationColor}m${inputString}\x1b[0m`;
}

With my web hat on, this does need a test to ensure the correct endpoints are called in fallback scenarios (if we're going that route). Otherwise, the unstable-stable flag or version checks need to be tested.

Overall this is looking better - thanks for adding the test! Just some points on the code itself and this should be fine to land.
